'lttng list -u session_name' doesn't behave as expected
One would expect
lttng list -u session_name to behave like
lttng list -k session_name and restrict the channel list output to the session's user-space channels, but that is not the case. Right now,
lttng list -u _session_name_ behaves exactly like
lttng list -u and lists all available user-space events: the
session_name argument is ignored.
